CALENDER-ROLL.

SPECIFICATION forming part of Letters Patent No. 7 22,190, dated March 3, 1903.

Application filed July 28, 1902. Serial No. 117,239. (No model.)

To all whom it may concern: nal-brass d of an adj usting-screw g, centrally Beit known that I, FRED'C.

This invention relates to improvements in The foregoing description is that of a calcalender-rolls, the object thereof being to proender'roll hearing as usually constructed at 10 vide means for detecting at a glance whether the present time. As stated above, these rolls or not any of the rolls are out of line. As is will for one reason or another get more or well known, calender-rolls are run under exless out of alinement, and before this fact is ceedingly heavy pressure, and in order that discovered damage to avery considerable exthey may remain true it is essential that their tent may be done to the rolls.

Each side of the center line g on the rod is, which is marked 50 journal-box c is cored out, as at f, to permit on the rod opposite the end of each roll by the introduction between the end of the box means of a plumb-line when the calender is next to the upright and the side of the jourset up. These center marks 1 having been made, it is very easy to adjust the ends of each roll so that the indicating-finger will stand exactly on this center mark and the rolls thus be adjusted in perfect alinement as to their axes. If after such adjustment a roll gets out of line, it may be instantly detected by a glance at these indicating-fingers.

While in the above description the construction of the component parts of the device have been specifically described, I do not wish to be understood as confining myself absolutely to this construction, as the invention is one of those which is capable of being worked out in many difierent ways.

While the invention has been described herein as applied to calender-rolls, it obviously is equally applicable to other machinesas, for example, to the end of a crank or other shaft.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. The combination with a roll or shaft, of an indicating-pointer adapted to be operated by the lateral movement of said roll, whereby horizontal movement of the latter may be indicated.

2. In combination, a laterally-adjustable roll or shaft, a laterally-immovable support therefor, a sliding member on said support, and means of engagement between said member and said roll, whereby the movement of the roll relative to its support may be indicated.

3. The combination with a laterally-adjustable roll or shaft, of an indicating-pointer adapted to be operated by the lateral movement of the roll, an immovable support for said pointer, and means for adjusting said roll laterally.
